Could the route to the stars be paved not by impossible physics, but by spacetime itself? A new warp drive model has been revealed by a group at the Advanced Propulsion Laboratory (APL), one which for ...

The nature of light and photons reveals deep insights into spacetime, showing how they traverse without time, reshaping our ...

When speaking of our universe, it's often said that "matter tells spacetime how to curve, and curved spacetime tells matter how to move." This is the essence of Albert Einstein's famous general theory ...

A team of researchers led by the University of Warwick has developed the first unified framework for detecting "spacetime fluctuations"—tiny, random distortions in the fabric of spacetime that appear ...

What if our biggest idea about reality is built on a hidden misunderstanding? A new philosophical look at space-time challenges the popular view that the past, present, and future all exist together ...

A team of scientists has used X-ray and gamma-ray observations of some of the most distant objects in the Universe to better understand the nature of space and time. Their results set limits on the ...

Post-spacetime physics refers to the idea that our familiar 4D spacetime is not fundamental but emerges from deeper structures—whether geometric (fiber bundles, higher-dimensional manifolds), quantum ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

Most of today’s leading theoretical physicists have a shared perspective about what the next revolution in physics will look like. They think reconciling Albert Einstein’s general theory of relativity ...

Mind-bending materials called quasicrystals have an orderly structure, but without a regularly repeating pattern. They’ve been found in meteorites and the debris from the first atomic bomb test.

One of the most awkward parts of writing a book is that, eventually, authors have to ask people for “blurbs” – the endorsements that you see on the cover of a book, encouraging you to buy it. I am now ...

The quantum revolution in physics — whose 100th anniversary we have just celebrated — taught us that at the most basic level the world is bizarrely different than it seems. But, we appear to only have ...
